The technical documentation mentions that ADC2 supports power and peak detection. It nearly goes as far out of its way as possible to not give any sort of concrete details. What, exactly, is this? What pins does it use? There are very, very few registers that mention PWDET, it is mentioned without r...

Soooo, nothing? It appears to me that everyone does do a reset of the hardware before doing an output from I2S again so it looks like maybe you have to. But, no confirmation on that? And, why should it be necessary? The hardware can't be trusted to work properly without constantly resetting it?

So, the basic gist of it is that I'm outputting on four pins to drive the four inputs to an H-bridge. You ask, why didn't I output two pins only? Because I want the h-bridge to be able to idle too. So, four pins it is, one to each transistor gate, idling means the P-channel mosfets are held high and...

This is just an uneducated guess. But, could the scheduler be taking control and processing another task behind your back? The processor is dual core but still there could be other tasks running on your same core. That and interrupts. If an interrupt comes in it might cause phantom delays that you c...

I suspect it will be difficult to make it work reliably. The ESP32 can toggle pins at 80MHz. So, a 10Mhz serial interface should be well within the limits of the hardware in terms of input and output speed at the pins. However, the general rule of thumb I've heard about serial ports on the ESP32 is ...

It's called ESP Exception Decoder and is found here:

You are allowed to specify a wait time of 0. In that case if there are no pending messages to receive then the function just immediately terminates. So, you can poll for CAN frames that way.

As Mstackoverflow was basically saying: what you have is NOT J1939. Such traffic would have extended ID frames (29 bit) and the data byte format would be different too. What you actually have doesn't even appear to be ISO-TP or anything else somewhat standard. Instead it looks kind of like it might ...

CollinK - Reading your answer a few times... is it possible to send the whole Can message in binary to the PC and decode it later. Yeah, sure, I do it all the time. I have whole complicated programs that run on the embedded and PC side (in this case ESP32RET on the ESP32 and SavvyCAN on the PC) but...

Whatever Espressif has planned for the future chip...please do NOT remove the CAN bus controller!! I agree. Though, I would not mind if the CAN controller were upgraded. Say, to a CAN-FD compatible interface. I really, really like the MCP2517FD chip. Now, I know that can't just be put verbatim into...
